I realize I'm far out on deap philosophical water here...
My line of reasoning is something like this:
At a certain point in time the person (or persons) in front (or back) of you stops being just a pearson and becomes an attacker (in your mind that is). I don't think this is a question of just semantics.
Should we try, through practice, to push this transition forward in time and eventually stop it from happening at all?
Further more I don't like the concept that at a certain time a conflict is inevitable. I believe that you always have a choice. A choice to attack, a choice to defend your self etc. By practicing we simply get more posible choices.
